HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 782, 613 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 782, 613 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 782, 613 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 782, 613 is 1.
HCF(782, 613) = 1
HCF of 782, 613 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 782, 613 is 1.
Highest Common Factor of 782,613 is 1
Step 1: Since 782 > 613, we apply the division lemma to 782 and 613, to get
782 = 613 x 1 + 169
Step 2: Since the reminder 613 ≠ 0, we apply division lemma to 169 and 613, to get
613 = 169 x 3 + 106
Step 3: We consider the new divisor 169 and the new remainder 106, and apply the division lemma to get
169 = 106 x 1 + 63
We consider the new divisor 106 and the new remainder 63,and apply the division lemma to get
106 = 63 x 1 + 43
We consider the new divisor 63 and the new remainder 43,and apply the division lemma to get
63 = 43 x 1 + 20
We consider the new divisor 43 and the new remainder 20,and apply the division lemma to get
43 = 20 x 2 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 782 and 613 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(43,20) = HCF(63,43) = HCF(106,63) = HCF(169,106) = HCF(613,169) = HCF(782,613) .
